Nelson and Slaven, played by Greig Pickhaver and John Doyle, established their Olympic commentary style with the critically acclaimed The Dream with Roy and HG, which was the breakout hit of Seven's Sydney 2000 summer Olympic Games coverage.

They subsequently fronted The Ice Dream, at the 2002 Winter Olympics in Salt Lake City, The Cream, at the 2003 Rugby World Cup, and The Dream, at the 2004 Athens Olympics.

The pair also fronted an online show The Dribble mit HG und Roy, covering the 2006 FIFA World Cup, and on radio The Golden Ring Show, covering the 2008 Beijing Summer Olympics.

"Ten has given us a great opportunity to look closely at the new Russia and to catch up with old friends newly released from prison," Slaven said in a statement.

"This will be a great games for our Australian winter superstars like Dale Begg-Smith and to unearth new stars the world is yet to hear about."

Nelson described it as a "dream come true to be back at the Olympic coalface."

"There is no greater thrill in the world of sport than seeing young, fit Australians wearing the green and gold standing on the top step of the podium, wearing medals and grinning," Nelson said.

Ten's head of sport David Barham described the deal as a "key signing" for Ten.

"They are proven medal winners, they bring vast Olympic experience and we are looking forward to their insights on Russian culture," Barham said.

Ten's coverage of the XXII Sochi Olympic Winter Games airs from February 7 on Ten, One and Tenplay.
